Why is water considered a chemical compound, not a mixture?
Quick fact
Water is made up of two hydrogen atoms and one oxygen atom, forming the molecule H₂O.
Why this is interesting
Did you know that water isn’t just H₂O—it’s a fundamental building block of life?

Understanding Why is water considered a chemical compound, not a mixture?
A chemical compound has a fixed ratio of elements, while a mixture can vary in composition.
A deeper explanation
Water (H₂O) is formed by covalent bonds between hydrogen and oxygen atoms. This results in a unique molecular structure that gives water its properties such as high surface tension, polarity, and ability to dissolve many substances.
